How do you get said achievement Ive done quiet a few of the generic quests for Vex and Delvin, and still nothing. So how do I get it and the wiki wont tell me.

Do enough of Vex and Delvins quest in a certain hold and Delvin will give you a special job for that hold. Do each holds' special job and you get the achievement.

you need to do 5 individual misc. quests for each of the holds, once u complete 5 you will get a "special quest" for that hold, so whenever u get a random quest if its not for that particular hold you need, quit and keep trying till you get what you need, dosent affect anything only your overall quests for the guild, which really means nothing, i have them all beat and that acheivement and have negative4 quests completed for the guild, kind of a pain and a long drawn out proccess, but it works

When you complete all the cities main quests you will be called back to the guild for your guildmastery stuff. You need to complete 5 miscellaneous missions in: Markarth, Riften, Whiterun, Windhelm and Solitude. After those five missions you will recieve a special quest that 'completes' the city.

So.

Get quests from Vex/Devlin. What I did was drop quests if they were not in the city I wanted to complete at the time e.g. I had already completed the specific quest for Riften, but Vex offered me another mini quest there so I dropped it and kept on rerolling till I got a quest in Markarth.

Keep doing this till you complete 5 missions in each city, completing the unique, special missions when they pop up.

Thanks, this one seems like a very tedious achievement to get, along with the "Get a bounty of 1000 in each hold."

It's not that bad. The Thieves' Guild jobs are all very easy, and you have fast travel to get from place to place.

This, but you don't need to do missions in Riften as the guild already has a patron there.
